  • Patent number: 7837182
    Abstract: A dust boot retention system includes a jounce bumper having an end portion with an outer diameter and an annular recessed groove adjacent to the end portion. A dust boot is attached to the jounce bumper and has an upper flange including a radially inwardly extending portion and an axially extending portion extending from an innermost portion of the radially inwardly extending portion. The axially extending portion has an inner diameter smaller than the outer diameter of the end portion of the jounce bumper. A rate ring secures the dust boot to the jounce bumper. The rate ring includes an inner diameter smaller than the outer diameter of the end portion of the jounce bumper. The rate ring includes an annular recessed channel in a first end thereof for receiving the axially extending portion of the dust boot.

  • Publication number: 20090194920
    Abstract: A suspension device is provided having a casing that defines a cavity, which further defines a stop face. A piston is slidably disposed in the cavity and offset from the stop face, wherein the piston is operable to move axially relative to the stop face when a force is imparted on at least one of the casing and the piston. A spring is disposed in the cavity and between the stop face and the piston, wherein the spring communicates with the piston and the end face and is operable to compress as the piston moves toward the end face and absorb the force. A friction damper is disposed in the cavity and operable to generate frictional drag between the piston and the casing, wherein the frictional drag inhibits axial movement of the piston in the cavity.
